Medical history, epicutaneous test for mercury derivatives.
Epicutaneous tests with the various mercury compounds for the detection of a type IV allergy show variable, not always reproducible results. The epicutaneous test should be performed with standardized 1% mercury(II) amine chloride in petroleum jelly and 5% amalgam in petroleum jelly. Exposure for 24 or 48 hours and late readings (at least 72 hours) are required. Due to the wide range of morphological reaction possibilities, the test should only be carried out by experienced, dermatologically versed allergologists.
Allergic reactions to phenyl mercury borate or acetate or to other mercury compounds (e.g. thiomersal) are at best vague indications of the presence of an allergy to inorganic mercury.
TherapyThis section has been translated automatically.
- If there are no clinical symptoms, amalgam fillings can be left in place.
- In case of clinical symptoms as well as temporal and topographical connection with an amalgam filling, fillings should be replaced, e.g. with ceramic or biogold fillings. Any further contact with mercury should be avoided.
- As a precaution, amalgam should be avoided in any future cavity restoration.
Note(s)This section has been translated automatically.
Doctors are often confronted with the question of an allergy to amalgam in dental fillings. Mostly complex, elusive symptoms are expressed. They are often also made aware by a dentist or a "holistic" arguing dental technician of the possibility of material replacement as a solution to their health problems.
